Description

一种妥尔油脂肪酸咪唑啉磺酸盐表面活性剂及制备方法Tall oil fatty acid imidazoline sulfonate surfactant and preparation method 技术领域Technical field
本发明属于表面活性剂技术领域，具体涉及一种妥尔油脂肪酸咪唑啉磺酸盐表面活性剂及制备方法。The invention belongs to the technical field of surfactants, and specifically relates to a tall oil fatty acid imidazoline sulfonate surfactant and a preparation method.
背景技术Background technique
妥尔油脂肪酸是由C 16、C 18链长的直链脂肪酸构成，主要成分为油酸、亚油酸等不饱和脂肪酸、少量饱和的棕榈酸、硬脂酸和松香酸构成，妥尔油脂肪酸来源十分丰富，是粗妥尔油通过蒸馏分离得到的，妥尔油(又称塔尔油、术浆浮油)是松木碱法制浆的副产物。目前，直接将妥尔油作为原材料的利用较少，其利用量约占粗妥尔油总量的10％，绝大多数粗妥尔油通过多级分离，然后再将这些原料制成其他产品。全球范围内，每年的妥尔油产量巨大。然而在我国，对妥尔油产品的深加工，并用于生产具有高附加值的表面活性剂和洗涤剂等方面的开发几乎是空白。在妥尔油中占有很大比例的脂肪酸成分正是表面活性剂工业的重要原料之一。 Tall oil fatty acids are composed of straight-chain fatty acids with C 16 and C 18 chain lengths. The main components are unsaturated fatty acids such as oleic acid and linoleic acid, and a small amount of saturated palmitic acid, stearic acid and rosin acid. Tall oil The source of fatty acids is very rich. It is obtained by distillation and separation of crude tall oil. Tall oil (also known as tall oil, tall oil) is a by-product of pine alkali pulping. At present, the use of tall oil directly as a raw material is rarely used, and its utilization accounts for about 10% of the total crude tall oil. The vast majority of crude tall oil is separated through multiple stages, and then these raw materials are made into other products. . Globally, the annual production of tall oil is huge. However, in our country, the development of the deep processing of tall oil products and the production of surfactants and detergents with high added value is almost blank. The fatty acid component, which occupies a large proportion in tall oil, is one of the important raw materials for the surfactant industry.
咪唑啉型表面活性剂是一种应用性能优良的表面活性剂，几乎与所有其他类型的表面活性剂配伍都会产生良好的协同效应，在日用化工、金属缓蚀、石油开采、纺织、印染等领域有着非常广阔的应用前景。如今，市面上销量最多的咪唑啉表面活性剂产品是月桂酸咪唑啉，含量一般为35％左右，巴斯夫、广州天赐、广州星业、上海发凯等均有销售，主要是由于所用的季铵化试剂易水解，产品粘度太大，影响传质效率，进一步影响咪唑啉中间体的转化率、产品稳定性和外观等。妥尔油脂肪酸主要由长碳链直链脂肪酸构成，用它合成的咪唑啉产品粘度会更大，而妥尔油脂肪酸成分的复杂性，也对产品工艺提出了很高的要求。Imidazoline surfactant is a surfactant with excellent application performance. It can produce good synergistic effects when compatible with almost all other types of surfactants. It can be used in daily chemical industry, metal corrosion inhibition, petroleum exploitation, textile, printing and dyeing, etc. The field has very broad application prospects. Today, the most sold imidazoline surfactant product on the market is imidazoline lauric acid with a content of about 35%. BASF, Guangzhou Tianci, Guangzhou Xingye, Shanghai Fakai, etc. are all sold, mainly due to the quaternary ammonium used The chemical reagent is easy to hydrolyze, and the product viscosity is too large, which affects the mass transfer efficiency, and further affects the conversion rate, product stability and appearance of the imidazoline intermediate. Tall oil fatty acids are mainly composed of long carbon chain straight chain fatty acids, and imidazoline products synthesized with it will have greater viscosity. The complexity of tall oil fatty acid composition also places high requirements on the product process.
表面活性剂在我国发展和更新速度较快，大宗表面活性剂的生产已完全满足国内需求，但多数技术水平要求较高、性能独特的绿色高效高值表面活性剂仍需大量进口。本发明针对市场对绿色可再生生物质原料表面活性剂的需求，以源自松木造纸行业副产物的妥尔油脂肪酸为原料，制备了一种妥尔油脂肪酸咪唑啉磺酸盐表面活性剂，为我国妥尔油产品的深加工提供一条新的路线，可极大的提高妥尔油产品的利用率，提高产品附加值，具有显著的经济效益与社会效益。Surfactants are developing and renewing rapidly in my country. The production of bulk surfactants has fully met domestic demand, but most of the green, high-efficiency and high-value surfactants with high technical requirements and unique performance still need to be imported in large quantities. In response to the market’s demand for surfactants for green and renewable biomass raw materials, the present invention uses tall oil fatty acids derived from the by-products of the pine wood paper industry as raw materials to prepare a tall oil fatty acid imidazoline sulfonate surfactant. It provides a new route for the deep processing of tall oil products in our country, which can greatly improve the utilization rate of tall oil products, increase the added value of products, and have significant economic and social benefits.
如今妥尔油脂肪酸相关的应用一般是合成妥尔油酸酯类并应用在切削液中，这种产品是油溶性的，应用范围非常有限。专利CN104193774A用妥尔油脂肪酸、二乙醇胺和硼酸为 原料合成了一种妥尔油酸二乙酰胺硼酸酯，可直接稀释用于金属加工中的切削液，这种产品应用面非常狭小。S.-F.Wang等以妥尔油脂肪酸和羟乙基乙二胺为原料，用二甲苯做携水剂，合成了妥尔油酸咪唑啉中间体，再与3-氯-2-羟基丙磺酸钠合成妥尔油酸磺酸盐。妥尔油酸咪唑啉中间体中的二酰胺副产物含量太高，得到的产品色泽较深和稳定性较差，并且用二甲苯作溶剂，二甲苯是3类致癌溶剂，不利于工业化推广(S.-F.Wang,T.Furuno,Z.Cheng.Synthesis of 1-hydroxyethyl-2-alkyl-2-imidazoline and its derivative sulfonate amphoteric surfactant from tall oil fatty acid.J.Wood Sci.49(2003)371–376.)。Nowadays, the related application of tall oil fatty acids is generally to synthesize tall oil esters and apply them in cutting fluids. This product is oil-soluble and has a very limited range of applications. Patent CN104193774A uses tall oil fatty acid, diethanolamine and boric acid as raw materials to synthesize a tall oil acid diacetamide borate, which can directly dilute the cutting fluid used in metal processing. This product has a very narrow application range. S.-F.Wang et al. used tall oil fatty acid and hydroxyethyl ethylenediamine as raw materials, and used xylene as a water-carrying agent to synthesize a tall oil acid imidazoline intermediate, which was then combined with 3-chloro-2-hydroxyl Sodium propanesulfonate synthesizes tall oil sulfonate. The content of diamide by-product in the intermediate of tall oil acid imidazoline is too high, the product obtained has a darker color and poor stability, and xylene is used as a solvent, xylene is a type 3 carcinogenic solvent, which is not conducive to industrial promotion ( S.-F.Wang,T.Furuno,Z.Cheng.Synthesis of 1-hydroxyethyl-2-alkyl-2-imidazoline and its derivative sulfonate amhotericsurfactant from tall oil fatty acid.J.Wood Sci.49(2003)371 -376.).
